That's bothersome. I can't see anything in the log regarding it, but it looks pretty clear to me to be some sort of loading failure. Here's the extract, for convenience, from start of load to start of exit:

I'm afraid I don't know where to take this. Like I said, I've encountered this myself on the Mac version, but was never able to find a fix, and I would guess it's a bug deeper down. Best I can do is pray to Luis!
